HFO, MDO/LFO - Main data

Engine speed Fuel type Cylinder output (MCR) Mean effective pressure

[rpm] [kW] [bar] 900 HFO + DMC 295 23.1 MDO / LFO 310 24.3 1000 HFO + DMC 310 21.9 MDO / LFO 325 23.0

The Mean Effective Pressure of the W26 engine can be calculated as follows:

General formula

pe = P / (n * 0.01416)

pe = Mean effective pressure [bar] P = Output per cylinder [kW] n = Engine speed [rpm]
